.ASH-CAN-DUMPING APPARATUS.

Application led .Tune 5, 1926.

Our invention relates to improved apparatus to lift ash-cans and similarheavy containers and dump the contents thereof into trucks to be hauledaway. One of its objects is to provide improved means to convenientlyengage and lift the ash cans successively to a position where thecontents of the cans may be dumped into the bed of a truck. Anotherobject is to provide improved means adapted to conveniently dump thecontents of the container into the bed of a truck. Another object is toprovide lifting means adjustable to cans of different diameters. Anotherobject is to provide an improved suspending apparatus adapted to becarried by the truck and to suspend the cans and swing them intoposition to be dumped and to swing them back to position to deposit theempty cans upon the ground. Our invention also comprises certain detailsof form and arrangement and combination of components, all of which willbe fully set forth in the description of the accompanying drawings inwhich,

Fig. 1 is a diagrammatic view illustrating a hoisting apparatus mountedupon a truck and embodying our improvements.

Fig. 2 is a detail of the can supporting apparatus of Fig. 1.

Fig. 3 is a diagram illustrating the can supporting apparatus beinglowered into position over a can preparatory to hoisting and dumping thecan.

Fig.' 4 is a view similar to Fig. 3 illustrating the next stage in theoperation of lifting and dumping the can.

Fig. 5 is a view similar to Figs. 3 and 4 illustrating the linal stagesof dumping and returning the can to a vertical position.

Fig. 6 is a view similar to Fig. 2 illustrating a modification of thecan supporting apparatus.

The accompanying drawings illustrate the preferred embodiments of ourinvention in which represents a truck body 16, the truck wheels drawn upin the street close to the curb 17 preparatory to lifting a series ofash cans, one of which 18 is illustrated in Fig. 1 as lifted a shortdistance from the sidewalk 19. In practice hotels, office buildings,.apartment buildings and similar build- Iings require at frequentintervals to remove considerable quantities of ashes, which iscustomarily done by moving them in large ash cans to the sidewalk wherethey are lifted and their contents dumped into a Serial No. 113,991.

truck and hauled away. This operation ol lifting the cans and dumpingthem requires two or more operators and puts a severe strain upon theoperators, liable to cause injury thereto, in addition to beingexpensive.

Mounted upon the truck body is the pedestal 2O of a crane which in turncarries a crane arm 22 which is journaled by means of a series ofconical rollers 24 constituting a step-bearing to the pedestal near theupper end of the pedestal and is provided with a stem or tubular shaft25 projecting downwardly over the pedestal and provided at its lower endwith an annular bearing 28 which takes the lateral thrust or strain ofthe lower end of said shaft 25 against the ei;- terior wall of thepedestal. rlhe crane arm 22 may thus be rotated relative to thepe'destal to lift the cans from the sidewalk, and swing them intoposition to dump the contents of the cans into the truck body. The cranearm is also mounted detachably by tapered dovetail joints 23 and adaptedf" to be readily lifted from the truck and stored until again requiredfor use. An eye is adjustably mounted near the free end of the cranearm. A bolt 29 serves to lock the stem 25 and arm 22 to the pedestalagainst rotation when desired.

Any type of block and tackle apparatus is adapted to be employed to liftthe cans from the sidewalk anddum-p their contents into the truck. Asillustrated a pair of pulley blocks 30 and 31, and a chain or iiexi'blelcable 32 are employed, and the free end of the cable may be drawn over afriction or clutch wheel 33 and pawl 34 carried yby the crane armadapted to grip the cable and hold the can in an elevated positionduring the dumping operation., and thereby provide for the cans beinglifted and dumped by a single operator if desired.

The can supporting `and dumping apparatus comprises an upper yoke 40'having an eye 41 by means of which it is suspended from the lower block31., a lower yoke 42, and a ring 43. The ring 43 is provided on oppositesides with stud Ashafts o-r trunnions 44 and 45 upon which the free endsof the yoke 42 and also the free ends ofthe yoke 40 journal. The ring 43:may if desired be an unbroken ring, as illustrated in Figs. 3,

4 Iand 5, but is preferably constructed as illustrated in Figs. 1 and 2or Fig. 6 of two parts, a-main ring section to which the lili) ITXtrunnions 44 and 45 are attached, and a gate section 5l hinged at 52 atone end to one ent of the section 50 and provided at its opposite endwith a latch or with an eye to register with one or more similar' eyes54 carried by the section 5() so as to be locked thereto by inserting apin 4S through the eyes 53 and 54 to lock the gate section 5l to themain section 50. In Figs. l and 2 we have also shown three screw rods 56threaded through the ring sections 50 and 5l, and provided at theirinner ends with shoes 5T adjustable to engage cans of differentdiameters, and at their outer ends with han-d wheels 58 by means ofwhich said screws may be conveniently adjusted to diii'erent positions.In the modification of Fig. 6 we have shown a ring of rectangularpattern composed of the main section 59 providedL with trunnions 60 and6l, and a gate tion 62 hinged to the main section 59 at (3S, andprovided at its free end with an eye (S4 adapted to register with a pairof similai eyes 65 upon the section 59 andto be latched thereto byinserting a pin through the eyes 64 and 65.

there cans of a single diameter are to be lifted the ring may becontinuous and without the screws 56. To lift the cans the ring andyokes are lowered from the crane arm as indicated in Fig. 3 so that thering 43 encircles the can and the lower yoke 42 is turned on thetrunnions 44 and 45 to pass downwardly ,along one side of the can. Whenthe lower end of yoke 42 reaches the bottom of the can the can is tiltedas indicated in Fig. 4 sufficiently for the lower end of the yoke 42 toenter and occupy a central position beneath the can while the ringsupports the middle and upper portion of the can laterally.

The hoisting apparatus is then actuated to lift upon the yoke 40, andthrough the trunnions 44 and 45 upon the yoke 42, thereby lifting thecan from the sidewalk to a sufticient height where it can be swung uponthe crane arm to any desired position ready to dump the can. The dumpingoperation is effected as indicated in Fig. 5 by turning the can, thering, and the yoke 42 upon the trunnions 44 and 45 with reference to theyoke 40 until the can is sutliciently inclined or inverted to dump ordischarge its contents into the truck body, after which the can, ringand yoke 42 are restored to substantially the position shown in Fig. land the can lowered to the sidewalk and the can released from the ringand yoke 42 by an operation substantially the reverse of thatillustrated in Figs. 3 and 4. TWhere the diameters of the cans vary, thescrews 56 may be einployed to support the cans of less diametercentrally with reference to the ring. Also where a number of cans areassembled in close relation the gate in the side of the ring may beopened to admit the can in place of lowering the ring down over the topet" the can.

The apparatus herein shown and described is capable of considerablemodification within the scope of the claims without departing from thespirit of our invention.

lVhat we claim is:

l. A can hoisting apparatus comprisingl an upper yoke, a lower yoke anda ri` y' said `yokes and ring being pivotally relatively connected uponan axis common to both yokes and said ring to engage and hoist a cansubstantially as specified.
